MOTOR VEHICLE.

Application filed June 16,

- and is illustrated as embodied in a vehicle having common operating connections for a valve in the fuel-supplyingconnections, as for example the usual choke valve, and for a device controlling the engine-cooling means, which device may be a valve in the waterciroulating system, a radiator shutter, a clutch for the fan, or a shutter for the conduits of an air-circulating system. Preferably the operating connections operate successively on the cooling device, and on the choke valve or its equivalent, so that the cooling device may be operated independent- I ly of the choke valve.

The various novel features of the invention, which are particularly pointed out in the appended claims, will be apparent/from the following description of several illustrative embodiments shown in the accompanying drawings, in which: I

Figure 1 is a diagrammatic side elevation of part of a motor vehicle having common controlling means for the choke valve and the water cooling system;

Figure 2 is a similar view of part of an automobile having common controlling means for the choke valve and the radiator shutter;

Figure 3 is a similar view of part of an automobile having common controlling megns for the choke valve and a fan clutch; an

- Figure 4 is a similar view of part of an automobile having common controlling means for the choke valve and 'a shutter for an air cooling system. I

In the arrangement shown in Figure 1, there is an engine 10 under a hood 12 extend ing from a radiator 14-t0 a dash 16 at the front of the cowl 18, the cowl carrying an instrument board 20 in the usual drivers compartment. The engine drives the usual fan 22, and has fuel-supplying means including a manifold 24- and a carbureter 26 with an air intake 28 having a choke valve 30' of any usual or desired form. The engine also has a cooling system including a water jacket with a lower connection '(not shown) from the radiator, and with an upper connection 32 to the water jacket. Where the same parts appear in Figures 2,3, and 4 they are indicated by the same reference characters.

According to the present invention, a valve 34 in connection 32 is arranged to be operated 1924. Serial No. 720,327.

by a rod 36 to restrict or shut oif the circulat1on of the cooling water in warming up the engine. Rod 36 has an operating handle 38 formed with ratchet teeth to engage the lower edge of an opening in instrument board 20 to hold it in any desired position of ad- ]ustment. The rod 36 also carries an ad justable stop 40 which engages, after. sufficient lost motion to restrict passage 32, a bellcrank lever 42 on the dash 16, the bellcrank lever operating choke valve 30 by means of a link 44 connected to an arm 46. Thus the Water circulation may be restricted VYlthOlll'j operating the choke valve, while a single control member operates both valves 30 and 34.

In the modification shown in Figure 2, rod 36 operates a radiator shutter having interconnected pivoted leaves 234, and which controls the flow of cooling air past the radiator 14 and the engine 10. The rod 36. carries the stop 40 operating the choke valve 30, as before. In Figure 3 the rod 36 operates a lever 334 against the resistance of a spring 336 to relieve the ressure on a friction or slipping clutch 338 or the fan 22, thus stopping or slowing up the fan before operation of the choke valve. in this modification is directly connected to a sleeve 342 on rod 36, which is engaged by the stop 40. In Figure 4 the rod 36 operates a shutter 434 in a passage 432 forming art of a circulation system for cooling air, w ich includes an air-circulating fan 422 discharging radially air which has passed about The link 44 the engine cylinders. It will be noted that it is not my intention to limit its scope to these particular embodiments, or otherwise than by the terms of the appended claims. I "claim: 1. In a motor vehicle, an engine, a device for controlling the temperature of the;

engine, a mechanism controlling the fuel mixture supply to the engine, a single control means, a posltive connection between .said control means and said device, and a lost motion connection between said control means and said mechamsm. v

2. A motor vehicle comprising, in combination, an engine, a device for controlling the tem erature of the engine, a device for controlling the fuel mixture supplied to the engine, and a single operating member directli connected to the first device and havdevice.

ing st-motion connection with the'second 3. A motor vehicle comprising, in combination, an engine having a choke valve,

.trolling the efiect of the cooling means on the engine, an operating member for said device, a stop on the operating member, and.

a connection to the choke valve operated by the stop. p J

5. A motor vehicle comprising, in combination, an engine having fuel-supplying nation" a drivers com artment an en ine having fuel-supplying means with" a valve, a

radiator and a radiator shutter, a shutteroperating rod accessible from the drivers compartment, a stop on the rod and a valveoperating connection operated by the stop for controlling said valve.

7. An engine, cooling means mixture supplying means, a device to control the action of the cooling means, mechanism to control the fuel mixture supply means and a single control means to operate said device and mechanism, whereby the device is first operated and thereafter the mechanism.

In testimony whereof I aflix my signature.
